720 We need to be careful in how we match section names because of the support
721 for wildcard characters. For example suppose that the user has invoked
724 --set-section-flags .debug_*=debug
725 --set-section-flags .debug_str=readonly,debug
726 --change-section-address .debug_*ranges=0x1000
728 With the idea that all debug sections will receive the DEBUG flag, the
729 .debug_str section will also receive the READONLY flag and the
730 .debug_ranges and .debug_aranges sections will have their address set to
731 0x1000. (This may not make much sense, but it is just an example).
733 When adding the section name patterns to the section list we need to make
734 sure that previous entries do not match with the new entry, unless the
735 match is exact. (In which case we assume that the user is overriding
736 the previous entry with the new context).
738 When matching real section names to the section list we make use of the
739 wildcard characters, but we must do so in context. Eg if we are setting
740 section addresses then we match for .debug_ranges but not for .debug_info.
742 Finally, if ADD is false and we do find a match, we mark the section list
